The aFe Silver Bullet throttle body spacer installs between the throttle body and intake manifold, where its serrated/helix design creates turbulence in the incoming air to sharpen throttle response and build low-end torque and horsepower. Machined from T-6061 billet aluminum, the serrated entry also cancels the intake whistle common to helix-only spacers. It uses factory mounting points for a bolt-in install and fits Toyota Tundra, Sequoia and Land Cruiser plus Lexus GX460/LX570 models with the 5.7L V8.
